To all whom it may concern Be it known that I, GEORGE BEIuLnR, a

roe and State of New York, have invented certain new and useful Improvements in Photographic and Developing Apparatus, of

p which the following is a specificat1on..

/ This invention relates tophotog'raphy and particularly to novel means. for subjecting:

film to the action of fluid,.the said invention relating especially to means for submergin-g or pressing'the so that it will" descend a in the flui a The invention herein relates particularly to that class of photographic apparatus which have for their objects the severance of film into lengths preferably coextensive or practically coextensive in area with. the area of the exposure thereon," the subjecting of the said film to theactionof developing fluid and the delivery of the developed portion of the film to a liquid bath,-'preferablyj hypo, so that? the severed sections of 1 film after delivery to the hypo may be pressed under the surface of the hypo in order that the coated surface of the film may be af-' view of'the state. of the art when fected uniformly throughout its' surfaceorthe exposed areathereof.

I" have used the term by that term, I meansensitized flexible material capable of use in conjunction with developing meansadapte'd to subject the film to the action of fluid after it has. been ex posed to light. a a v V c With the foregoing and other objects in View, the invention consists in the broad idea to be set forth in the claims during the prosecution of the application, the said claims to :be of such scope as to give protection commensurate with the inventive act in the said invention was produced.

In describing the invention in detail, reference will be had 1 to the accompanying drawlngs forming part of, this specification wherein like characters denote corresponding parts in the several views, and in which r Figure 1 illustrates a vertical sectional view of a fragment of a photographing and developing apparatus embodying the invention;

vFig. 2 illustrates a perspectiveview of the Specificationof Letters Patent. Application filed January 20, 1916. Serial No. 73,169.

Fig. 3 illustrates a perspective view of a detail employed' in connection with, the invention." Y y In these drawings 4 denotes a casing, 5 an ing fluid and stretching it overthe fluid in the receptacle 12 prior to its being cut, it being understood that after itiis cut, the severed section of film will fall into the receptacle 12 which preferably contains hypo' or other fixing fluid. 1 The means for operating the feed rolls and actuating the cutting member or knife may be of any well known construction, but they are here shown as essentiallycomprising or including-a constructiomthe details of which are more fully illustrated in.

'my application filed June 11, 1914, Serial Number 844516. W

As the said application discloses means for operating the drawing rod 11, the illustration of said means is here reproduced in part and comprises the guides 13 which enter slots 14 in the sliding block 15. The

sliding blocks are moved longitudinally of the guides-by means of chains, one of which (16) is here illustrated. it being understood that there is a duplication of these parts on opposite sides of the casing. A shaft 17 is suitably rotated and carries a sprocket wheel 18'which is engagedby the sprocket chain 16. Furthermore, the] sprocket chain 18 engages a sprocket wheel 19 mounted to rotate; near the opposite end of the casing and as the-sprocket chain is moved alternately in opposite directions through the rotation of the shaft 17 the blocks 15 are reciprocated on their guides. By reason of the movement means: associated with film drawing means; and a citizen of the United States of-America, and resident of Rochester, in the county of Mon exposing chamber, 6 the drawing roll for pulling film 7 through the exposing cham-v ber and delivering it to a receptacle 8 which of the parts just described, film is drawn from the receptacle and after it has been severed, it falls into the receptacle 12 con taining the fixing fluid r other liquid preferably adapted to act on the coated surface 7 of thc film. It has been found desirable, to more effectually subject the film to the action of the fixing fluid, to mechanically agitatc the film after it has been deposited in the fluid or to press the said film so that it will descend in the fluid and various means have been devised by me for eflecting this result.

In the present embodiment of a device designed to accomplish that result, I have I provided additional blocks 20 and 21 having slots'22 and 23 respectively toreceive the edges of the guides 13 so that the blocks 19 v and 20 movein unison with the blocks 15 during their reciprocation in the casing.

The blocks 19 and 20 are here shown as having arms 2% and respectively, each of "which issecured to acorresponding block 15 by a fastening such as a screw 26, thus forming a fram-elikestructure which is slid- I able on the guides Within thecasing.

The blocks 19 and 20 may be regarded as bearing blocks in that in the present embodiment of the inventioiu one of the said blocks has an moerture 27 to receive an end of a shaft 28, whereas the opposite block 20 is recessed to form a seat 29 for the reception of the opposite end of the said; shaft the arrangement of parts beingsuch that l preferably the shaft may-rock slightly in the 7' bearing blocks'for a purpose to'bepresently explained.

The arms 30 extend from the shaft 28'and their outer or lower ends are-provided With apertures 31 in'which a shaft 32- is rotatable,

: the, said shaft being supplied with disks 33 so secured on the shaft as to be rotatable therewith, although the said disk may be in dependently-rotatable on the shaft.

The 'disks shafts 32 and arms 30'are preferably constructed of material: which is not injuriously affected by photographic chemicals, such as fixing fluid and the-Weight of these materials should be such as to insure submergence of a film or films \vithwhich they come in contact. It has been found in practice that a film submerging device made in accordance with the invention is efiective to ride over the film andpress it into the fix ng fluid. Durm'g the operation of an apparatus embodying the invention, it has been observed that film which; has'fallen into the fixing fluid after beirigcut is en- 1 gaged by the disks during the time that the drawing rod is being returned to normal po sition, which is the position in which it appears illustrated in Fig. 1, and that the said engagement of the disks with the film results in moving the film longitudinally of the receptacle and that this movement continues until the end edge of the film remote from the disks has engaged the Wall of the receptacle. Movement of the film is then arrested and further movement of the disks results 1n the disks traveling over the film and pressagitation of the film results.

As the films increase in numbeuwithin the receptacle,. the arms may SWlllP, sllghtly sothat the disks may be elevated to accom- V modate themselves to the increased thickness of the layers of film Wliichthey over-ride.

"lvitlt'the use, of the inimersin device of the; invention avery slight amount of power is required for its. operation and as there is nomovement of the immersing member in and out of the fluid, there is no appreciable agitation of the fluid due to the reciprocatory motion of theimmersing device with relation-to the receptacle.
